Microsoft’s March 2025 Patch Tuesday update addresses a significant number of security vulnerabilities in Windows 10, 11, and Server, including patches for seven zero-day exploits already being actively exploited. This critical update is crucial for protecting your systems from potential attacks.
The update, detailed in the Microsoft Security Update Guide, tackles several serious flaws, some of which allow remote code execution, enabling attackers to run malicious code on a victim’s system. One such vulnerability, CVE-2025-24993, requires an attacker to manipulate a local user into performing specific actions, like mounting a compromised virtual hard disk image. Microsoft assigns this vulnerability a severity rating of 7.8, highlighting the urgency of applying the patch.
Several other vulnerabilities also involve virtual hard disk images. As reported by The Register, CVE-2025-24991 could allow attackers to gain unauthorized data access, while CVE-2025-24984 could enable the insertion of malicious information into log files. The update addresses three additional actively exploited vulnerabilities and six other critical flaws.
The Zero Day Initiative describes the number of actively exploited vulnerabilities in Windows as “extraordinary” and urges system administrators to prioritize implementing these security patches. They also highlight the Microsoft Management Console Security Feature Bypass Vulnerability, CVE-2025-26633, which has reportedly already affected over 600 organizations, emphasizing the need for swift action.
In addition to the Windows updates, Adobe also released its Patch Tuesday updates, addressing vulnerabilities in various software applications, including Adobe Acrobat Reader, Substance 3D Sampler, Illustrator, Substance 3D Painter, InDesign, Substance 3D Modeler, and Substance 3D Designer. While none of these Adobe vulnerabilities are currently known to be actively exploited, it’s still highly recommended to update your software to maintain optimal security.
This Patch Tuesday update is a crucial step in mitigating serious security risks. Updating your Windows systems and Adobe software promptly is vital for safeguarding against potential cyberattacks.
